Hi, All I do the following similiar search against AD and openldap respectively with ldapsearch command. For AD: ldapsearch -x -D "cn=admin,cn=Users,dc=jacky,dc=org,dc=cn" -b "cn=Users,dc=jacky,dc=org,dc=cn" -w 11111111 -H "ldap://x.x.x.x:389"; "sAMAccountName=user1" For openldap: ldapsearch -x -D "cn=admin,dc=jacky,dc=com" -b "ou=users,dc=jacky,dc=com" -w 11111111 -H "ldap://x.x.x.x:389"; "uid=user" I capture all the packets for above two searchs with tcpdump and I find that AD server will send search response(including search result entry & search result) in ONE packet while openldap will send search result entry and search result independently in two packets. My question: Is how to send search response back(in one or more packets) implementation specific? Thanks, Jacky
